Hi, All.
  I've got a problem like this:
      input some insturctions like
                syms x y
                min(x,y)
   in the workspace.Then get the following error :

??? Function 'min' is not defined for values of class 'sym'.

Error in ==> min at 34
  builtin('min', varargin{:});

In the other side, I try to use abs function like this,
                syms x
                abs(x)
Then get the correct answer.How to solve this probelm?

pls help me ,thank you in advance.
